So I finished testing the second half today. Today at 55mph I pulled 25.844mpg and at 60mph I got 28.333mpg. So my car definitely gets better gas millage at 60 then it does at 55.
Next time I go out to the same customer I will drive both directions at 65 and report the numbers.

No problem. Now I just hope that I can get better millage at 65mph then 60mph because I don't think I have the patience to drive a really long distance at 60mph.

Even if it costs more gas, think of the time savings. Time = $. Therefore, it's at least a wash, and possibly a gain depending on how you leverage your time.

You've done a lot so far. If you are in the mood, would it be possible to do a MPG at 80. Yea, really.
I can't, no speedo or odometer.

For your sake, I hope you do. For the sake of my theory, I hope you don't. My guess would be that your mileage at 65 would be similar to your mileage at 55, but for a different reason. Being wind resistance over lugging. |

So I drove out to Scottsdale, AZ today and I drove at 65mph to the border, filled up and then drove 75mph the rest of the way into Scottsdale. At 65mph I got 25.083mpg and at 75mph I got 22.043mpg. So it looks like I do get the best mpg at the highest vacuum in my car.

Ok, this was my last test. I ran from Scottsdale to the border (192.2 miles) at 80mph and got 20.055mpg. In my Cobra the rpms at 80 were 2400. |
